What diseases can canker sores cause?

5 major symptoms to be alert to oral cancer.

1. Canker sores do not heal.

Oral cancer often appears in the form of ulcers, with raised edges around it, bumpy and covered with necrotic tissue, and obvious pain.

Many oral cancer patients have the experience of white ulcers or blisters on the inside of the buccal mucosa, which usually occur when there is stress, poor sleep or changes in eating habits (such as lack of fruit), and usually heal within two weeks; If it does not heal for more than two weeks, it needs to be tested to rule out the possibility of cancer.

2. Color change of oral mucosa.

Oral leukoplakia and erythema proliferative are often precancerous.

The normal oral mucosa is pink, and the color of white or red polarization is abnormal. If it is red and white, it is a more serious condition, and if there is a dark red with white dots on the tip of the tongue, there is a high suspicion of cancer.

3. The pain is obvious.

In the early stage, there is general** or only a local abnormal friction sensation, and the pain is obvious after ulceration, and as the tumor further invades the nerves, it can cause ear and sore throat.

4. Swollen lymph nodes in the neck.

Oral cancer often metastasizes to nearby cervical lymph nodes, and sometimes the primary lesion is very small, or even the symptoms are not obvious, but metastatic cancer cells can be found in cervical lymph nodes. Therefore, if the lymph nodes in the neck suddenly enlarge, the mouth should be examined.

5. Dysfunction.

Tumors may invade the opening and closing mouth muscles and mandibular joints, resulting in limited opening and closing movement.

Early detection and early detection can significantly increase the rate of tumors, so once the above relevant signals are found, you should seek medical attention in time.

The other way around, one should ask what diseases can cause canker sores.

The ** of canker sores is as follows:

1. Digestive system diseases and digestive system dysfunction: oral ulcers are related to gastric ulcers, duodenal ulcers, and colon ulcers. Studies have shown that 30%-48% of people with canker sores have digestive disorders such as bloating, diarrhea or constipation.

Some women will have mouth ulcers during menstruation or before and after menstruation, which can only be temporarily relieved by medication**, usually accompanied by symptoms such as dry mouth, irritability or dry stool.

3. Mental factors: some patients may be related to autonomic nervous dysfunction in the case of mental tension, emotional fluctuations, and poor sleep conditions.

4. Genetic factors: both parents have ** oral ulcers, and the probability of their children developing ** oral ulcers reaches 80 -90, and if one parent has ** oral ulcers, the incidence of their children reaches 50-60.
